摘要

葡萄球菌空气部分的多种医学特性及有益健康影响。& Heldr。无性系种群。Raeseri表示需要进一步调查。采用喷雾干燥工艺对葡萄树提取物进行微胶囊化处理,使不稳定的活性成分分散保存在保护性基质中。采用两种进气温度(120和140ºC)将raeseri提取物包封在由麦芽糊精(10%、20%和40%)或乳清蛋白(40%)组成的基质中。测定了喷雾干燥对其理化性质、总酚类、总黄酮含量及单个类黄酮苷含量的影响。40%乳清蛋白处理增加了容重(238.46 mg/mL),降低了吸湿性(14.27%)。此外,高麦芽糖糊精浓度可获得最高的工艺效率(63.46%)、最高的水溶性指数(86.40%)和最低的吸水指数(5.71%)。此外,不含麦芽糊精的粉末中黄酮类苷含量较高。综上所述,在适当的条件下,采用喷雾干燥技术制备的葡萄球菌粉末可以被认为是一种新的功能药用成分。

Microencapsulation of Sideritis raeseri Boiss. & Heldr. subsp. raeseri Extract Using Spray Drying with Maltodextrin and Whey Protein
Multiple medical properties and beneficial influence on health attributed to the aerial parts of Sideritis raeseri Boiss. & Heldr. subsp. raeseri indicated the need for further investigation. S. raeseri extracts were subjected to microencapsulation by the spray drying process in order to disperse and preserve unstable active compounds within a protective matrix. Two inlet air temperatures (120 and 140 ºC) were applied for the encapsulation of S. raeseri extract in a matrix composed of maltodextrin (10, 20, and 40%) or whey protein (40%). The effects of spray drying on physico-chemical properties, contents of total phenols and flavonoids, as well as of individual flavonoid glycosides of the obtained powders were determined. The 40% whey protein treatment increased bulk density (238.46 mg/mL) while it decreased hygroscopicity (14.27%). In addition, the high maltodextrin concentration of the S. raeseri powder resulted in the highest process efficiency (63.46%), the highest water solubility index (86.40%), and the lowest water absorption index (5.71%). Moreover, powders produced without maltodextrin were characterized by greater content of flavonoid glycosides. Overall, the results suggested that S. raeseri powders produced using spray-dried technique under adequate conditions could be considered as a novel functional and pharmaceutical ingredient.
